Interpretation:
The Van’t Hoff factor of CaCl2 in the solution with given concentration and osmotic pressure is to be calculated.
Concept introduction:
The properties of a solution that depends on the number of solute particles present in solution but do not depend on the nature of solute particles are called as colligative properties.
The four colligative properties of solution are vapor-pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure.
The word, colligative, means binding of particles together.
The osmotic pressure of a solution is given by the expression as follows:
π=iMRT
Here, π denotes osmotic pressure, i denotes Van’t Hoff factor, M denotes the molarity of solute, R denotes the universal gas constant (0.0821 L⋅atm/mol⋅K), and T denotes the temperature.
The conversion of temperature from degree Celsius
